This invention relates to improvements for a revolving shelf unit and is an improvement on Patent 1,692,609, issued to Bernard S. Bassett .on November 20, 1928.

The primary object of this invention is to provide a revolving shelf unit, which may be easily attached to any type or size of cabinet or cupboard and which will serve to retain various and sundry articles in secured placement free from ants and other insects.

Another object of this invention is to provide a plurality of shelves, which are unitarily joined to form a revolving unit, the unit being laterally or vertically adjustable to accommodate various sizes and shapes of shelves.

A meritorious feature of this invention resides in the provision of support castings, which serve to rotatably support the shelf unit and also serve to retain a liquid, powder or other insect-repelling insecticide.

Another meritorious feature of this invention resides in the provision of means for adjustably supporting a plurality of shelves in a cabinet, the shelves being adjustable vertically and laterally.

These and ancillary objects and other meritorious features are attained by this invention, a preferred embodiment of which is set forth in the following description and illustrated in the accompanying drawings, wherein:

Figure 1 is a Vertical sectional view of a cabinet showing this invention rotatably retained therein, the shelf unit being shown in vertical sectional view;

Figure 2 is a transverse sectional view taken Substantially on the plane of line 2-2 of Figure 1;

Figure 3 is a cross sectional view taken substantially on line 3--3 of Figure 1;

Figure 4 is a group perspective view of the structure provided by this invention; and

Figure 5 is a view in perspective of the bottom support plate.

Referring now more particularly to the drawings, wherein similar characters of reference designate corresponding parts throughout, the numeral ll] designates a cabinet or the like, of any particular or desired size or shape, having a base l4 and a top wall IS.

A shelf unit, [2, is adapted for rotation within the cabinet, the same being supported by the base 14 and the top I6. The shelf unit I2 comprises a dished base plate I8 which is attached by any suitable securing means 20 to the base M. Integrally formed with the base plate l8 and extending centrally therefrom is a vertical rod 22.

1 Claim. (01. era-e05) A top support plate 24 is secured by suitable fastening means, such as screws 26, to the top 16 of the cabinet and has a centrally depending tube 28 integrally formed therewith. The oppositely disposed tubes 22 and 28 serve to rotatablysupport the shelf unit !2 within the cabinet.

The shelf unit comprises a bottom shelf 34, having an annular peripheral raised flange 36 formed thereon. A frusto-conical attaching or supporting plate 38 is secured to the bottom of the shelf 34 by any suitable means. The central portion of the closed minor end of the plate 38 is recessed or indented, as at 42', and is detachably seated on a ball bearing 35, which is supported by the rod 22.

Attached to the flange 36 of the bottom shelf 34 and extending vertically therefrom in equidistant fashion are standards 40, which are adapted to support a plurality of shelves 42. Attaching apertures 44 are formed in the standards 40 in vertical spacement and, in association with apertures formed in the raised peripheral flanges 46 of the shelves 42, serve to attach the shelves to the standards.

A top plate 48, having a centrally extending tube 50, which is adapted to receive the depending tube 28 of the top plate 24, is attached to the extending portion of the standards 40 by any suitable means. The means provided comprises an adjustable angle iron 52, having elongated slots 54 formed in the angular extremities thereof. The angle irons 52 are attached by bolt assemblies 56 to the standards 40, through the medium of the attaching apertures 44 therein, and are attached to the support plate 48 by means of the apertures 58 circumferentially spaced therein. Bolt assemblies 60 or other fastening means serve to adjustably secure the angle irons to the top plate 48 through the apertures 58.

Thus, it can be seen that the shelves 46 may be placed horizontally at any desired vertical placement along the standards 48 through the apertures 44. Accordingly, the unit revolves around the tubes 28 and 22, through the medium of the tube 58 and the ball bearings 30 seated in the recess 42' of the base plate or support 38. Of course, suitable insecticides such as powder or a liquid may be retained in the base plate l8 and in the top plate 48 to repel insects, such as ants, from advancement onto the shelves.

Of course, it is to be apparent that various sizes and types of shelves may be employed and retained by the standards, the vertical spacement between the shelves being adjustable as desired and required. Also, the provision of the shelves,

which are solid, enable various articles to be retained thereon and prevent dust and spilled food from falling to the shelves below.

However, since various other objects and purposes of this invention will become apparent to those skilled in the art upon a perusal of the foregoing description and in view of the accompanying drawings, it is to be understood that certain changes may be efiected therein, as coming within the spirit of the invention and within the scope of the appended claim.

Having described the invention, what is claimed as new is:

In combination with a cabinet having a top wall and bottom wall, an insect-proof shelf unit comprising a dished base plate mounted on the bottom wall and having an upstanding rod, a supporting shelf rotatably mounted on the rod, anti-friction means disposed between said rod and shelf, a plurality of vertical standards carried by the supporting shelf, a plurality of horizontally disposed shelves adjustably secured to the standards, a top dished supporting plate having radially extending angle irons adjustably secured to the upper ends of the standards for vertical adjustment with respect to said top sup- 2,590,880 r -1 i p N 4 porting plate, said angle irons being adjustably carried by said top supporting plate, an upstanding tube carried by the plate, a member secured to the top wall of the cabinet, and a downwardly extending rod carried by the member and received in the tube.
